Abstract
An electrode management solution for neuromonitoring applications such as electroencephalography (EEG) procedures provides for the verification of the locations and connections of electrodes. The brain is modeled as a volume conductor and an expected attenuated signal generated by an electrical signal present in the form of an electrical dipole at any other point in the brain is calculated. A known signal is connected between electrodes at 'presumed' locations. This action generates a defined electrical field which can be measured between any of the other electrode locations. The amplitude and phase of the measured signals are a function of the input signal, the volume conductor, and the geometric relations of the two electrodes. By comparing the expected values with the measured values, the relation between the electrodes is verified.
